Either way, it's a lot of work and dedication.
The online question bank is becoming less and less a tool to be relied upon. Only perhaps 60-70% of the last set of exams were in there, where previously it was more like 70-80%, so you really need to know the subjects too.
I just don't think I would've had the dedication for distance learning, although the learning would be more spread out, and you may use more than 2 sittings.
